This Snail’s Eyes Grow Back: Could They Help Humans do the Same?

Andy Fell — August 06, 2025 - 12:30pm

Human eyes are complex and irreparable, yet they are structurally like those of the freshwater apple snail, which can completely regenerate its eyes. Alice Accorsi, assistant professor of molecular and cellular biology at the University of California, ��ԭ��, studies how these snails regrow their eyes — with the goal of eventually helping to restore vision in people with eye injuries.

Psychedelics and Non-hallucinogenic Analogs Work Through the Same Receptor, Up to a Point

Teeth chronicle the past. Much like trees, they grow in rings and these rings, or growth marks, act like a record of development.

"Teeth retain the chemical signatures at the time when they were grown, starting at birth and ending in your late teens,” said Diana Malarchik, a Ph.D. candidate in the UC ��ԭ�� Department of Anthropology. “Based on this anatomy, I can sample these growth rings and get nitrogen signatures and create a dietary timeline.”

Toddlers’ Eye Movements Predict Ability to Judge Memories, New Research Suggests

Andy Fell — June 11, 2025 - 9:00am

The simple act of looking and comparing may be the first step toward learning how to judge what we remember, a skill that is fundamental to learning and making decisions.

New research from the University of California, ��ԭ��, has found that toddlers who tend to look more closely at and compare paired images during a memory task are more aware of the accuracy of their own memories a year later. This finding connects the earliest process of seeking information with the developing ability to judge the accuracy of memories.
